New since version 0.6:

You can now add notes with an inversed behavior (adding a note when the pattern isn't matched). In the case below, we use the same pattern, once to ask for numbers only and than to thank the user for following the rule. Additionaly the note is now displayed on top of the input field with the "notePosition" option.

Each note has a class with the same name as the type of the note, so you are free to create any kind of notes, you don't have to name them note, warning ... just use a name that can be used as a CSS class and everything is fine.
